WINDOW-CLEANING APPARATUS. 9

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed September 23, 1909. Serial No. 519,274.

To all whom it may concern: '13s it known that I, PETER F. DALY, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin VVindow-Cleaning Apparatus, of which the following is aspecification.

This invention relates to devices or apparatus adapted for cleaningwindows and I particularly applicable for-use on the front windows ofstreet cars, railway cars, and motor vehicles or other. conveyances. Itsobjects are to'provide a simple and efficient means for removing therain, vapor or moisture=,-from the-outer side of the window, together:withf suitable operative mechanism whereby the cleaning device may be0perated by the driver or motorman without leaving his position in thecar or other vehicle.

A preferred form of my invention, showing the mechanism foraccomplishing these ob ects, is shown in the accompanying drawin s, inwhich-f igure l'is l side view of one end of a street car equipped withmy window clean ing device,'p'arts being broken away to show theinteriorconstruction; Fig. 2 is a front view of the car shown in Fig. 1;Fig. 3 is an enlarged sectional detail showing the window cleaner andreturn mechanism; Fig. 4 is a' detail'of one of the clips for holdingthereturn-spring tube; Fig. 5 is a detail showing the adjustable 'capfor the foot ,plung'em'Fign dis a sectional plan view taikefilonlline'fis ii 'of Fig. 3; and Fig. 7 is a front View of theparts shown in Fig. 6.

As indicated in these drawings, 8 represents a street car of anyordinary construction, although it will be understood that my improvedwindow cleaner may also be applied to windows of other vehicles, or infact to windows of any kind where it may be'adaptdto be used. The sashof the front window of the car, to which my deviceis applied, isindicated at 9, and the pane thereof, at 10. Along the posts or frameforming the front of the car, I provide guides 11-1-1, preferablyofrectangular cross-section and open at one side, as"

shown most plainly in Fig. 6. These guides are provided w1th lugs 12,having screws .13lw ich' engage with posts or other suitable part: ofthe car frame. Slides or carriages 14 engage with the guides 11 andsupport ber-s15 with friction shoes 16, these shoes be ing held againstthe iner sides of the guides 11 by means of springs 17, as shown inFigs. 3 and 6.

The squilgce or cleaning device proper 18 comprises a long bar ofangular cross-section, as indicated in Fig. 3, the main portion of whichis provided with trunnions or gudgeons 1!) which engage with the blocks15 of the slides or carriages 14, while the inwardly extending portionis provided with a wiper 20 of rubber or other suitable material adaptedfor cleaning a window, this wiper being held in position in any suitablemanner, asby means of the screws 21 which clamp it within the groove inthe edge of the bar. Lugs or pro ections 22 extend 1nwardly from thisbar, acent to the trunnions 19 and engage with clamps or clips 23whichare secured to the operating ropes 21 and 25. One set of these ropes orcords is for drawing the device down, and the other for returning it tonormal position; of course, continuous ropes may be used, if so desired.The ropes or cords 24 pass up and over guide rollers or pulleys 26 and27 in the upper end of the guides 11 and then extend inwardly throughthe front of the car where they are secured to the ends of tensionspringsQS preferably arranged within the tubes 29, these tubes beingsecured in the top of the car by means of clamps 30. Adjustment'of thesprings 29 is provided by having the ends of the springs secured toslidable nuts or threaded members 31 which engage with screws 32 passingthrough caps 33 in the ends of the tubes 29, these screws being held inadjusted position by means of nuts 34.

The ropes 25 extend downwardly and engage with winding drums or sheaves35 secured on'a cross shaft 36 which is held by means of hangers 37-from the bottom of the car 8. The shaft 36 is provided with a pinion 38which engages with a segmental rack 39 on'the end of a lever 40 pivotedat 4:1 to suitable hangers or supports 42 from the bottom of the car.The opposite end of the lever 40 is slotted to receive a roller 43 inthe end of afoot plunger 44 which extends upwardly through a bearing 45in the bottom-of the car, and is provided at its top with an adjustablecap 46, this cap being held in adjusted position by meansof a lock nut47, as indicatedpaatieulaply; in Fig. 5. At the upper end of thebearing.

45 is secured a I'UdQbQI washer or buffer 48 which is engaged by thelocknut 47' when the plunger 44 is pressed downwardly to its spring-pressedshoes 16 will cause a sufficient friction on the sides of the-guides '11so that.

lowermost position. A spring 49 is secured tot-he inner end of-the lever40 and -tolthebottomof'the car, andis adapted to return the lever' andplunger to as indicated in Fig. 1;

The particular" form of my invention shown in the drawings will bereadil under stood from the above description. ation, the e motormanordriver presses his footoiftrthe cap of the plunger 44, w-hiehcauses theinner endof-the .lever 40 to be swung -downwardly, thereby; turning thesegmental rack 39,-rwhich rotates the pinion 38,"thereby causing theshaft 36 and sheaves or drums 35 -to revolve: and wind up the. cords or'cables 25; On-account of the upperends of these cables being securedto"the.

barof'the squilgee atsome distance from thecenters of the trunnions 19,they cause-the bar to be swung toward the window pane, therebycausingthe wiper 20'rto .be drawn forcibly against and down across thesurface of' the pane. -This will efiectivelyremove'any moisture,dirt-or- :dustfrom; the

front of the: pane, leaving the glass clean so'that' the driver ormotor'man'mayreadily;

see out of thecar. It willlbe noted that the the forward orswingingmovement-oftfhe squil'gee will be effected before the carria es orguides 15. start -to move downwarly, thereby insuring the closeengagement of the wiper '20 'with--the'- window pane. When the plunger44 has beenz-movedtothe end of its stroke, the'operator removes hisfoot.

from the cap 46, thereby releasing,- the plungerand allowing the spring49 to return the plunger and connected parts to. normal position.Simultaneously, the
